Recently, the CoGeNT collaboration reported weakly interacting massive particle candidate-signal events exceeding the known backgrounds where the light WIMP with large cross section is supported. Motivated by this issue, we analyze a light neutralino dark matter scenario with a very light CP-even Higgs mediation in the elastic scattering process, which provides the mass and direct detection cross section to explain the CoGeNT result. To be compatible with the result of LEP experiments, the… Expand

Light NMSSM neutralino dark matter in the wake of CDMS II and a 126 GeV Higgs boson
Recent results from the Cryogenic Dark Matter Search (CDMS) experiment have renewed interest in light (5{15 GeV) dark matter (DM) with a large spin-independent neutralino-nucleon scatteringExpand
CoGeNT, DAMA, and Light Neutralino Dark Matter
Abstract Recent observations by the CoGeNT collaboration (as well as long standing observations by DAMA/LIBRA) suggest the presence of a ∼ 5 – 10 GeV dark matter particle with a somewhat largeExpand
Light neutralino dark matter scenario in supersymmetric four-Higgs doublet model
A bstractWe examine a possibility to explain the signals of dark matter direct detection from DAMA and CoGeNT experiments, under the framework of supersymmetric extension of the standard model. ForExpand
Minimal hidden sector models for CoGeNT/DAMA events
Motivated by recent attempts to reconcile hints of direct dark matter detection by the CoGeNT and DAMA experiments, we construct simple particle physics models that can accommodate the constraints.Expand
Light dark matter from the U(1)X sector in the NMSSM with gauge mediation
Cosmic ray anomalies observed by PAMELA and Fermi-LAT experiments may be interpreted by heavy (TeV-scale) dark matter annihilation enhanced by Sommerfeld effects mediated by a very light (sub-GeV)Expand
Constraints on light WIMP candidates from the isotropic diffuse gamma-ray emission
Motivated by the measurements reported by direct detection experiments, most notably DAMA, CDMS-II, CoGeNT and Xenon10/100, we study further the constraints that might be set on some light darkExpand
Light Dark Matter and the Electroweak Phase Transition in the NMSSM
We analyze the stability of the vacuum and the electroweak phase transition in the NMSSM close to the Peccei-Quinn symmetry limit. This limit contains light Dark Matter (DM) particles with a massExpand
Secluded singlet fermionic dark matter driven by the Fermi gamma-ray excess
We examine the possibility that the dark matter (DM) interpretation of the GeV scale Fermi gamma-ray excess at the Galactic center can be realized in a specific framework-secluded singlet fermionicExpand
GW170817 constraints on the properties of a neutron star in the presence of WIMP dark matter
The properties of a neutron star are studied in the presence of dark matter. We have considered a relatively light Weakly Interacting Massive Particle (WIMP) as a dark matter candidate withExpand
